Prabhupada's lecture - Śrīmad-Bhāgavatam 1.15.21 - Los Angeles December 1, 1973
So these are actually knowledge. People are after something false. That is called māyā. Māyā means which is not actually fact, but we are after that. Similarly, this so-called advancement of civilization is māyā. It will be finished at any second, but they do not know. They do not know. It will be finished at any second. Even though we accept it, all right, Kṛṣṇa says in the Bhagavad-gītā, mṛtyuḥ sarva-haraś cāham: [Bg. 10.34] "I am the death, and I take away everything at the time of death." Either you take as a philosopher, scientist or rich man, capitalist, as soon as there is death... Just like you see, Hiraṇyakaśipu, he was very powerful, and as soon as Nṛsiṁhadeva appeared, everything finished. Now he is dying. You see? So people do not understand it, that without Kṛṣṇa, without God, without Kṛṣṇa consciousness, simply we are wasting our time, that's all, after false things. Everything will be useless. Today or tomorrow or day after. It will be useless, all useless. Real spirit soul-na hanyate hanyamāne śarīre [Bg. 2.20]—that we do not take care.
After finishing this false body, which will exist, the spirit soul, na hanyate hanyamāne śarīre [Bg. 2.20], which is never vanquished even after the annihilation of this body, we are not taking care of that, wherefrom it has come. People are ignorant, so foolish. They do not know. This is the ignorant, civilization of ignorance. Na māṁ duṣkṛtino mūḍhāḥ [Bg. 7.15]. They do not know therefore. In ignorance they are committing so many sinful life. For the satisfaction of the tongue, they are killing so many animals. Why? There are so many nice foodstuffs. Why you are committing these sinful activities? They do not know what is sinful activities or pious activities. They do not know.
